Hi all,

at http://www.slac.stanford.edu/~petrella/tmp/leptoncut_scanq2.eps
    http://www.slac.stanford.edu/~petrella/tmp/allcut_scanq2.eps

I have plotted the ratio between peaking background and continuum 
background yields wrt. q^2 cut (mx cut is 1.5) for lepton cut and all 
cut respectively. Unfortunately the trend is not constant.

The red line is the value of the ratio in the sample without any 
kinematic cut.
I have made this study on generic MC _without_ non BBbar continuum.

How can we proceed?
